摘　　要：研究并应用于三菱M701F4型燃气-蒸汽联合循环多轴机组冷态、温态、热态以及极热态启动过程。通过汽轮机对旁路逻辑控制优化,设计旁路阀最佳匹配开度,确保机组在启动过程中,锅炉汽包水位平稳,汽轮机主蒸汽冲转参数达到最佳,以保障机组启动安全并缩短机组启动时间。This paper studies and applies to the cold,warm,hot and extremely hot start-up processes of Mitsubishi M701F4 gassteam combined cycle multi-shaft units.By optimizing the bypass logic control of the steam turbine,designing the optimal matching opening of the bypass valve to ensure that the boiler drum water level changes steadily and the steam turbine main steam impulse parameters reach the best during the unit startup process,so as to ensure the safety and safety of the unit startup.Shorten the start-up time of the unit.

关 键 词：联合循环 汽轮机旁路控制 缩短启动时间
